Default USE_DEVFS to "1" so that the `makedevs' command is not run
at rootfs time by default. There are mainly two reasons to do so.
1. This will fix a build failure with initramfs-kexecboot-klibc-image.
2. Most of our images use a filesystem over /dev. Most of the time, it's
just devtmpfs. So we actually are using a filesystem over /dev.

Can you elaborate this error? is it something we can/should fix?

The underlying issue here is the extra pass of makedevs " makedevs:
No entry for root in search list "
At first I could not understand why that was *not* happening on my
builds then I realized we set
IMAGE_DEVICE_TABLES = "" in our machine.conf because we use devtmpfs
for all images.
qemux86 does instead inherit the default setting of image.bbclass so
it uses "files/device_table-minimal.txt"
